shipped a thing that generates video ads for my store, the AI part was easy and the prompting was 3 weeks of pain

generation was two days of work. prompting was three weeks and i still tweak it. adjectives do nothing. professional, high quality, engaging is wasted, cutting all of it changed the output zero percent. what moves it is specificity about the situation. not a woman holding a bottle, but a woman in a bathroom, morning light, already half dressed, mid routine. the setting carries the believability. found creatify's own notes on prompting after i'd learned most of it and it maps closely

AI 分析

痛点:AI视频广告生成的瓶颈不在模型,而在提示词:形容词无效,必须写出具体场景、光线、人物状态和动作,否则输出不可信且要反复调试。

目标用户:电商店主、独立站卖家、广告投手/代运营、短视频广告创作者,以及使用AI视频工具做投放素材的小团队。

证据:generation was two days of work. prompting was three weeks and i still tweak it. adjectives do nothing. professional, high quality, engaging is wasted... what moves it is specificity about the situation. not a woman holding a bottle, but a woman in a bathroom, morning light, already half dressed, mid routine. the setting carries the believability.

变现:订阅制提示词模板库+自动扩写工具,按生成次数/项目收费;面向代运营提供白标方案;高级版提供品类场景库、负向提示词避坑、A/B测试与团队协作。

MVP:做一个电商视频广告提示词生成器:输入产品、受众、卖点、投放平台,自动输出具体场景、光线、人物状态、镜头动作和负向提示词,并生成可粘贴到Runway/Pika/Kling/Creatify的完整提示词与分镜。内置3-5个高频品类模板,支持保存版本和A/B对比,2周内可用简单前端+LLM API完成。

竞品:Creatify、Arcads、Pencil、AdCreative.ai、HeyGen、Runway/Pika/Kling等通用视频生成工具

摘要:发帖人上线了一个为自己的店生成视频广告的工具,发现视频生成只花2天,但提示词优化花了3周且仍在调。核心洞察是“professional/high quality”等形容词无用,真正有效的是具体场景、光线和人物状态,例如浴室晨光中半穿衣的日常场景。该痛点指向一个面向电商卖家的AI视频广告提示词模板/自动扩写工具,但已有Creatify等竞品,且帖中未出现明确付费意愿或收入数据。
